I'm not sure what you mean.

Do you mean the Bookmarks Menu button that appears when you hide the Menu bar (View > Toolbars)?

I don't think so, if I hide the Menu bar I don't see a Bookmarks Menu. In this picture http://dl.dropbox.com/u/50261731/Open_File%20Menu%20.png an arrow points to an Options menu button. Select that Button and a list of options opens, one of which is "Show Bookmarks". I would like the Show Bookmarks option to be "ON" by default. Be aware that I am running SuSE 12.1 and I believe this Menu is provided by KDE integration "kmozillahelper", so my menu may be different from the default Firefox menu.

Apparently that is part of the default file picker of your OpenSUSE 12 Linux distribution.
I don't know how to customize that window, so you may try to ask that on the OpenSUSE support forum.

Thanks, I have already posted at SuSE Forum with looker but no commenters. I have also now posted at KDE Forum. The file picker is part of the KDE package. If I find something useful, I'll post it back here

I found a solution. See Thread at KDE Forum
